Detailed Description

Global lock for synchronization of VTK access.

When drawing a VTK scene by a render process, the mutual exclusion of access to the root node is indispensable. Any change of the scene graph has to be suppressed to avoid inconsistancy. Be aware that when writing or deriving a DAFFViz class that crucial access to the members of e.g. the vtkActor has to be locked! For ease you can use the DAFFVIZ_LOCK_VTK and DAFFVIZ_UNLOCK_VTK macros at the start and end of your method to provide for constistancy. If your renderer crashes for some esoteric matter you probably forget to lock the write access of your node.
